Show 770 MR. A. G. BUTLER ON [Nov. 3, ldmais and Callosune were formerly given. T. amina has much of the pattern of T. vesta and its allies on the under surface, but both sexes correspond more nearly with the T. ione group on the upper surface ; T. pholoe, from Lake N'Garni, is evidently a female allied to T. amina, but having two series of magenta spots across the black area of the primaries ; it may even be a dimorphic form of the female of T. celimene from Abyssinia, which is described as having two series of yellowish-white spots across this area : all these have the " ldmais " type of marking on the under surface. O n the other hand, the species from Somali, though on the upper surface much like T. amina and (evidently) T. pholoe, differs in having the under surface coloured more nearly as in T. zoe of Madagascar, a species intermediate in character between the T. halimede and T. ione groups, and thus links the so-called genera Ldmais and Callosune at another point, proving that even in their pattern they are completely linked and interlocked beyond the possibility of separation. 36. TERACOLUS EUPOMPE. Pontia eupompe, Klug, Symb. Phys. pi. 6. figs. 11-14 (1829). Two male specimens.-Thrupp. The males are chiefly distinguishable from the following by the magenta-shot colour upon the crimson apical patch, the usually much broader blackish inner border to this patch, and the more distinct markings on the under surface. 37. TERACOLUS DEDECORUS. Anthopsyche dedecora, Felder, Reise der Nov., Lep. ii. p. 184, n. 177 (1865). S . Duderi, 26th April; Bunder Maria, 27th April.-Yerbury. 6* 2 • Somali, 23rd December.-Thrupp. Some examples have no series of discal spots across the secondaries on the under surface, whereas others are nearly as strongly marked as in T. eupompe. This appears to be an inconstant character in the present species, as one out of three males from Duderi has these markings obliterated, a second has them half across the wing, and the third has a complete series and much resembles males of T. dulcis; the tint of the under surface also varies as in T. subroseus. 38. TERACOLUS COMPLEXIVUS, sp. n. cS . Upper surface almost exactly as in the male of T. omplialoides, differing in the orange instead of vermilion apical patch, and in the diffuse character of the posterior extremity of the black border. On the under surface it corresponds more nearly with the male of T. theogone, the apical area of primaries being precisely similar excepting that perhaps the red patch is a little more diffused ; the secondaries are however decidedly paler, of a clear pink colour with a broad grey costal border extending from the base to the brown costal spot; the discal brown stripe is well defined but the spot at the end of the cell extremely minute. Expanse of wings 45 millim. One male. January 2nd.-Thrupp. |
